Alright so I have the G0548ZP 2hp DC and I have purchased the bigger metal Super Dust Deputy from a friend for $50 because I didn’t have much success with my thien build sadly and the plywood was getting expensive.

Now my question is can I turn the motor mount so the impeller face downward going into the top of the SDD and remove the metal air travel arm and mount the filter ring sideways directly attached to the impeller body and run it with the canister sideways?

Not sure how this will effect the filtering capabilities I’m also think maybe I’ll just vent it outside and forget the canister completely as it would save space.

Questions, concerns, ideas…I’m all ears

Repositioning the impeller/motor has been done by many an LJer, myself included. I say go for it.

I would say NO to the collection ring/canister being mounted horizontally. The separation of the fines relies on gravity, to allow them to fall out of the air stream.

As far as venting outside….Whatever conditioned air (heat/AC) is vented would need to be replaced and reconditioned. Being in upstate NY, that could be an expensive reconditioning of replacement air. The answer relies upon the ability of your wallet, to pay for the reconditioning of the air.

I also think the blower can be oriented in any direction you want, and caution you to consider the heating impact. But I think you can mount the filter horizontally if you want. What would happen, I believe, is that the fines that get to the filter would gather on the bottom side. You’ll have to be cleaning it anyway at some frequency so it just means there are more fines at the bottom-most location than the balance of the filter. Obviously the flapper thingy isn’t going to do much. Ducting it outside would solve all this, and give you increased performance. The air flow slows as the filter gets clogged (duh). Without the filter you have the constant flow. Whether that’s worth the loss of heat is your call.

Well I suppose I could always call Grizzly CS and speak with one of the techs and ask if it has thrust bearings or not…as for venting it through the wall outside vs using the filter, not sure I’m quite understanding how great this heat or AC’d air loss will be.

What Ron said is true, but in a hobby environment I’m unsure whether it matters….like someone else mentioned this is a fairly common mod (turning the blower sideways). In any case, the heat loss question is one only you can answer. A lot of guys say it doesn’t make much difference; I guess I don’t think that applies to me (NW Ohio). But you may be moving 600-700 CFM of air out of your shop. In a 20X20×8 shop that’s an air change every 5-6 minutes; sounds like a pretty good heat loss to me even when you allow for the thermal mass in there.
